I'm rather picky at what I draw for some reason. Unless I really like what subject i'm doing, I'll put off drawing it. For that reason I might turn you down, but it's so I won't keep you waiting for six months sweatdrop
I do only traditional art. I don't have the technology for digital. I DO do anime with outlines but I prefer old school things. (Anime is actually a whole lot easier, but I like challenging myself) If I turn you down, even if you meet all these details, it's becasue I know that I'm not inspired to do the work (nothing wrong with that, I'm just not the person to draw your requests. I want to make sure I do my best on it ya know?)
Won't draw: Porn (traditional n***s are different stories... just not hentai-ish ideas please), a whole lot of people on one page, something offensive to a group of people (controversial is ok, just not racist or something to that effect), or non-humanish mythical creatures or monsters.
Like to draw: (things I'll tend to accept more) Ladies in gowns, Guys with capes, armor, swords, etc, landscapes I find pretty or challenging, scenes from various books, plays, TV shows, etc, fantasy landscapes/buildings/backgrounds, this you have to think about to understand, things unusal and bold, pirates, gods or goddesses, OCs that are very detailed and developed.
Chances are, If I like an OC well enough, I"ll draw him/her for free. That takes alot though, (I've been working on my people for eight years sweatdrop )I gotta really like and get the character.
